Hi,

  Which 3.11 were you using? Do you still have it? I mean the same script
still gives the same results in 3.11.X and in 3.12?

  Because in 3.12 there weren't many relevant changes to justify that
behavior. I don't know even were to start since the crash is happening
inside Windows not inside IUP.

  If the problem does not occurs in 3.11.X then I will test it here also,
because I run your sample only in 3.12.

  Sorry, to take so long to answer but this week I'm having several
meetings and presentations at Tecgraf.

Best,
Scuri
